Research object is describing natural beech forest dynamics in Naeba mountains by use of eco-physiological simulation model based on a permanent quadrat established in 1970. We summarized the following results.1) The newly developing of a simulation model is done successfuly, and converted to micro computer systems. The model can be used to analyze spatial different of light condition on a forest gap.2) It was not successful to describe spatial crown images by use tree crown photographs, and very difficult to applicate photo images instead use of crown projection area during research term causing a little experiences. We will try and continue to clear images of tree crowns finishing this research period.3) We recordeded the diameter data as a 25-year-data of the permanent plots along the altitude on northern slope in Naeba Mountains. All data were recorded in the computer systems. In the gap formations there are much tree species of pionear plants in beech forest as like Lindera umbellata var.membranacea, A cer rufinerve, A cer japoncum and its growth rates were twice times than that of beech. The reason which is not only light condition change but also its capacity change of photosynthesis affects the growth rates.

以1970年建立的固定样方为研究对象，利用生态生理模拟模型描述了根场山天然山毛榉林动态。1）成功地开发了一个新的仿真模型，并将其转换到微机系统中。该模型可用于分析林隙光照条件的空间差异。2）在研究期间，用树冠照片描述树冠空间图像并不成功，用照片图像代替树冠投影面积的方法也很困难，经验较少。3）以根场山北方海拔沿着固定样地的直径数据作为25年的数据。所有数据都记录在计算机系统中。在差距层中，有大量的山茱萸、红脉山茱萸、日本山茱萸等山毛榉林下的先锋植物，其生长速度是山毛榉林下的2倍。影响生长速率的原因不仅是光照条件的变化，而且是光合能力的变化。
